Use

Poly(methylhydrosiloxane) is a reducing agent. For example, it can be used for the reduction of esters to alcohols as well as the reduction of aldehydes and ketone. It can also be used for the reduction of phosphine oxides to phosphine. Recent study has also used it for conjugate reduction of α, β-Unsaturated Carbonyl and Carboxyl Compounds. Finally, it is also used in greener amine synthesis mediated by reductive amination which is an alternative to borohydrides. Poly(methylhydrosiloxane) is a reducing agent.

Polymethylhydrosiloxane(PMHS) is an easily handled,inexpensive,non-toxic,and mild reducing agent. PMHS is attractive as a substitute for more expensive or hazardous silanes or siloxanes and as the stoichiometric reductant in catalytic organotin-mediated processes. It can be cross linked by metal catalyst at low temperature to form waterproof membrane. It is used as waterproof agent of textile, glass, pottery, paper, leather, metal, cement and marble etc, especially in textile waterproof. It is used as insulator and cross linker of paper. Poly(methylhydrosiloxane) is used in the reduction of esters to alcohols, catalyzed by a combination of titanocene dichloride and either n-BuLi or EtMgBr. It is a safer alternative to triethoxysilane, B22063, for reduction of phosphine oxides to phosphines, catalyzed by Ti(O-i-Pr)4.
